Unquoted string defaults work through a quirk of Kconfig (undefined
symbols get their name as their string value), but look confusing. It's

Setting bit CR0.WP (bit 16) will inhibit supervisor threads from
writing to RO pages. It's a necessary flag to be set, and the constant
name CR0_PAGING_ENABLE didn't reflect the fact that the 16th bit was
being set.

_nvs_sector_is_used() never uses the offset argument. As a consequence,
it only check the first sector of the flash. Fix that.

The two functions that compute the crc16 when writing (nvs_append_close)
and when reading (nvs_check_crc) currently assume that the flash is
also mapped in read mode at address 0. This is not true on all SoCs, and
even less on an SPI flash.
Fix this by adding a new nvs_compute_crc() function which compute the
CRC16 of an entry using the flash using nvs_flash_read, in blocks of
write_block_size. This might not be the optimal size, but it keeps the
stack usage small.
Use this function in both nvs_append_close() and nvs_check_crc() instead
of accessing the flash from address 0.

Now that the flash writes are padded up to the write block size, there
is no need to have explicit padding fields in the _nvs_sector_hdr and
_nvs_data_slt structure. This allow to save space when the write block
size equals to 1 or 2

Writing more than the source buffer means that some random data,
possibly coming from the stack, ends-up in the flash. This could be
a security issue.

Reading more than the destination buffer means that data is overwritten
possibly on the stack. This causes unpredictable behaviours like
crashes.

Some SoCs do not allow shorter writes than the write block size, usually
when they have ECC memory. This patch first write all data in multiple
of the write block size and then do a last write with the data padded.
It uses 0xff as the padding byte to avoid wearing-out the flash.
nvs_append_close() is slightly modified to compute the crc16 that will
be put in the slot over the size defined in the header, to match the way
it is checked on read.

During normal use, a CoAP packet can be resent due to network congestion
and other causes. During block transfer the LwM2M client checks to make
sure the block received is the one we expect and if not generates a
"duplicate" warning. When this happened, we were releasing the reply
handler and when the correct block was received the client would
generate a "No handler" error.
To avoid releasing the reply handler too early, let's set the coap_reply
"user_data" field to an error condition (1). Then, once the reply
processing is complete we can check the user_data field to be sure that
it's ok to release the reply handler.

We want the struct to be packed to conserve space, but the
perms field needs to always be on a 4-byte boundary since
we do bitfield operations on it, arches like ARC require
that the sys_bitfield_* operations be aligned to a 4 byte
boundary.
Instances of struct _k_object will now be 4-byte aligned
if in an array (which they are), even though the members
are still packed.

In case ethernet cable is unplugged, stm32 ethernet driver triggers
an error, driver initialization fails and fw crashes.
This could be enhanced as in case not cable is connected, HAL
returns a Time out, and will resume its initialization when
cable is plugged.
Treat HAL timeout in ethernet driver initialization as a
recoverable error and continues driver init when it happens.
Tested with sample/net/dhcpv4_client. Start board with cable
unplugged. Wait some time before plugging the cable. DHCP request
is correctly performed when cable is plugged.

In SPI slave case the transceive should return either the negative
errno code in case of error or the number of frames received.
So, now:
1. the spi_stm32_get_err() routine already checks whether
the SPI cell got an error and returns -EIO in that case.
2. the transceive() routine always returns whatever the
spi_context_wait_for_completion() has returned, which
is either:
a. -EIO in case of error
b. 0 in spi_master ok case
c. the number of frames received in spi_slave ok case

Update board docs to reflect simpler method of flash/debug as

Signed-off-by: Gil Pitney <gil.pitney@linaro.org>
Previously, the cc3220sf platform could only be flashed using
TI UniFlash (or CCS) tools, requiring unique instructions.
Also, these procedures were not integrated with the standard Zephyr
build targets: 'flash', 'debug', 'debugserver'.
After installation of a TI OpenOCD v1.10 release, and other
one-time board setup, flashing and debugging can now be done
via OpenOCD/gdb, using the standard Zephyr build targets per
the Zephyr Application Development primer.

Previously, there was no easy command-line solution for loading
a Zephyr program to (internal) flash.
So, the default development method was to load via gdb/openocd
to SRAM and debug from there, thus making the cc3220sf platform
non-XIP (CONFIG_XIP=n) by default.
With new openocd v 1.10 updates from TI (git.ti.com/sdo-emu),
the image can now be flashed and debugged via gdb/openocd,
so the default will be changed to XIP (CONFIG_XIP=y).
